Geneva, 22 April 2011. Around midnight this night CERN1’s Large Hadron Collider set a new world record for beam intensity at a hadron collider when it collided beams with a luminosity of 4.67 × 1032cm-2s-1. This exceeds the previous world record of 4.024 × 1032cm-2s-1, which was set by the US Fermi National Accelerator Laboratory’s Tevatron collider in 2010, and marks an important milestone in LHC commissioning.
Latest press releases
Geneva, 31 January 2011. CERN1 today announced that the LHC will run through to the end of 2012 with a short technical stop at the end of 2011. The beam energy for 2011 will be 3.5 TeV. This decision, taken by CERN management following the annual planning workshop held in Chamonix last week and a report delivered today by the laboratory’s machine advisory committee, gives the LHC’s experiments a good chance of finding new physics in the next two years, before the LHC goes into a long shutdown to prepare for higher energy running starting 2014.
Geneva, 17 December 2010. Delegates attending the 157th session of the CERN Council today congratulated the laboratory on the LHC’s successful first year of running, and looked forward to a bright future for basic science at CERN1. Top of the agenda was the opening of CERN to new members. Formal discussions can begin now with Cyprus, Israel, Serbia, Slovenia and Turkey for accession to Membership, while Brazil’s candidature for Associate Membership was also warmly received.
Geneva, 6 December 2010. The ASACUSA1 experiment at CERN2 has taken an important step forward in developing an innovative technique for studying antimatter. Using a novel particle trap, called a CUSP trap, the experiment has succeeded in producing significant numbers of antihydrogen atoms in flight. This result is published today in the journal Physical Review Letters.
